Efficient synthesis of triarylamines catalyzed by palladium/N-heterocyclic carbene

A palladium(0)/imidazolium salt system as catalyst precursor proved to be effective, under the appropriately selected reaction conditions, for N-arylation of diarylamines and anilines with non-activated aryl bromides or chlorides to afford triarylamine derivatives. In most cases, excellent yields were achieved.
